In our vastly overpopulated (and growing)... as well as rapidly climate changing world, we will soon, be having more and more wars over oil
, potable water
, and with ocean rise causing lost
IF one wants to go with a large "power" boat anyway, AND have extreme energy efficiency, there are a couple of ways...
First off, for the "somewhat" less fuel, at similar or better accommodations...
A 45' power cat would have WAY more room than a 60' monohulled power boat
, and if built and kept relatively light, would consume perhaps half as much fuel.
Going even more extreme, at the expense of accommodations... I have seen a LARGE power "proa", where the main hull
is light, NARROW, and shaped like a large rowing shell's hull
, but still with plenty of room inside.
It had a small outrigger (1/3rd the main hull's size), that kept it stable in spite of the main hull's narrow, round bottomed WL.
Such a vessel would have EXTREME seaworthiness, compared to its monohulled counterparts. It would have a wonderful motion, even at great speed, while sipping a SMALL fraction of the other's fuel. It would also lend itself to a solar
array large enough to live in style, 100% self sufficiently!

This vessel might be 1/10th the fuel consumption
, for a given speed! If I had the bucks, & wanted to switch to "the dark side", this is what I'd do.
Otherwise, Steve Dashew has the best monohulled power boat
out there! Look it up.
